Smash Burgers with Caramelized Onions

Smash burgers are all about maximizing flavour and achieving crispy, caramelized edges. The key is to start with a loosely packed ball of ground beef and smash it hard onto a hot griddle for maximum browning and deep, savoury flavour. A slice of American cheese melts over the patty, adding rich, gooey goodness. To top it off, slowly griddled caramelized onions bring a touch of sweetness, balancing the burger’s crispy, juicy bite.

Heat the Alpine Outdoor Collection Rectangular Griddle over medium heat. Add olive oil and onions, spreading them out in the pan. Sauté the onions until they are softened and caramelized, stirring occasionally. After about 10 minutes, sprinkle the onions with ½ teaspoon kosher salt to help break them down, and add a little water to the pan if the onions seem too dry. Continue cooking for 30 to 45 more minutes, lowering the temperature if the onions begin to burn. Remove the onions from the griddle.

Meanwhile, divide the ground beef into four 4 oz (113 g) balls. Heat the griddle over medium-high heat. Place the balls on the hot griddle. Smash the burgers with a spatula, applying pressure, and sprinkle with salt and pepper. Cook the burgers for about 1 minute before flipping to the other side. The patties should begin to turn brown before flipping. Add a slice of American cheese on each patty and let it melt before removing from the griddle.

Split the buns in half and toast them on the griddle in the beef fat until golden brown. Assemble each smash burger and serve with shredded lettuce, tomatoes, pickles, and any desired condiments.
